Marantz MR255- parts

This is just a start for Crossing over Part# factory # 2SD738 (B or C) and 2SB702 (B or C) I am going by the factory service manual there will be more parts for now is there a high Quality replacement Transistors

Greetings,

The requested devices are not longer available, and appear to be in a package format which has fallen from favor. The 2SC3519 and 2SA1386 are a complementary pair that is currently stocked and in production, and which appear to show strong promise for being adaptable to the purpose.
